A new study shows older patients are still getting invasive cancer screenings.. even though there is little benefit. Researchers at UNC at Chapel Hill looked at about 27,000 seniors and found many with average risk and limited lifespan were undergoing invasive cancer screenings such as colonoscopies.. and many were likely to face *complications* from the testing.  Guidelines recommend *against* routine colonoscopies for the average patient 75 and older.

Hospitals are seeing an unexpected rise in deaths after urology surgery. That's according to researchers at Henry Ford Hospital in Detroit.  Doctors were expecting the death rate to *fall* as hospitals shift from inpatient to outpatient procedures.  But they found deaths are increasing for many common procedures involving stents and enlarged prostates. 

And there's word now that good neighbors could be good for your heart.  Researchers tracking the cardiovascular health of 5-thousand Americans over four years.. found those happy with their neighbors and surroundings had their risk of heart attack cut by 22-percent.
